A closure and filter for a multi-use water bottle. The closure has a main body having an outlet through which fluid passes to be consumed by the user and an air valve remote from the outlet to provide an air channel through the closure distinct from the fluid outlet to allow flow of air into the bottle as fluid passes through the outlet.

A device to provide in-line flavor for water or other liquid stored in a container. An example device includes a body having a cylindrical shape chamber formed therein, and an opening on a first end of the body. A cartridge holder fits within the chamber of the body and retains a flavoring therein for the water or other liquid. The cartridge holder has a plurality of openings for the water or other liquid to flow through. When a user drinks from the drinking end, the water or other liquid flows from the container and through the housing and mixes with a flavoring from the cartridge holder before being drawn through to the drinking end so that the user drinks a flavored water or other liquid.

Embodiments are directed to filtration container assemblies and methods of using the same. A filtration container assembly includes an outer container and a plunging assembly. The plunging assembly includes an inner sleeve, a filtration assembly, and a cap assembly having a pressing surface. When the outer container is at least partially filled with liquid, a user can exert pressure on the pressing surface of the plunging assembly to nest the plunging assembly within the outer container, using positive pressure to displace the liquid in the outer container through the filtration assembly into the inner sleeve. In some embodiments, at least a portion of a handle for the filtration container assembly may be a part of the pressing surface.

The present invention relates to water feeder technical field, more particularly to a filter assembly and a portable water feeder. The filter assembly includes a tray and a filter piece; the tray comprises a bottom frame with a bottom plate and a supporting wall and a supporting ring, the supporting wall is arranged around its circumference of the bottom plate and extends upward, the supporting wall and the bottom plate are jointly surrounded to form a cavity, and the bottom plate is provided with a number of filter holes; the supporting ring is arranged above the bottom frame and is connected to its top of the supporting wall, the filter piece is placed in the cavity. When the filter assembly is used, water flows from the filter hole into the filter piece, and the filter assembly has the advantages of simple and compact structure.

A bottle includes a main body having a receiving cavity, a straw, and a filtering arrangement. The filtering arrangement includes a guider housing disposed in the receiving cavity. The guider housing has a filter cavity, a plurality of liquid input slots communicating the receiving cavity with the filter cavity, and at least one liquid output slot connecting with the straw. The filter core is received in the filter cavity, such that when a suction force is applied through the straw, the liquid in the receiving cavity is arranged to pass through the liquid input slots and contact with the filter core for filtering unwanted substances from the liquid. Filtered liquid from the filter core is arranged to be discharged out of the receiving cavity through the straw.

A multi-functional water filtration apparatus includes an outer housing defining a receptacle for receiving a filter assembly and having an inlet port at a first end for intake of unfiltered water and being open at a second end. The filter assembly includes an endcap closing the second end of the outer housing and a filter element enclosed within the outer housing. The endcap has an outlet port for dispensing filtered water. The outer housing has a flow passageway extending between the inlet port and the outlet port. The filter element is disposed in the flow passageway and has an upstream side in fluid communication with the inlet port and a downstream side in fluid communication with the outlet port. In certain aspects, the filtration apparatus provides multiple attachment options. In further aspects, a method of filtering water is provided.

A purification device is provided that includes a porous container, purification media retained in the porous container, and a flow controller integral to the porous container. A purification device is also provided that includes a porous elastic container, purification media, and a flow controller. The porous elastic container has a pocket formed therein. The purification media is compressibly retained in the porous elastic container. The flow controller is elastically retained in the pocket of the porous elastic container.

The present invention discloses a filtering apparatus for filtering liquid and dispensing the filtered liquid into a bottle separate from the filtering apparatus. The filtering apparatus includes an elongated housing having an interior for holding liquid. The elongated housing includes an opening at one end and a ceiling at another end. The opening encompasses projections extending towards the center of the elongated housing. The filtering apparatus includes a filter configured for insertion and removal from the elongated housing. The elongated housing receives the filter at the interior through the opening. The elongated housing receives a bottle at the opening and the projections hold the bottle at the opening while preventing further entry of the bottle into the interior of the elongated housing. The interior holds liquid and allows the liquid to flow down through the filter. The filter filters the liquid as it flows through. The filtered water enters the bottle for subsequent use, storage or transport.

The present disclosure relates to a water treatment system, methods for treating water, and products for treating water. In certain embodiments, the present disclosure provides a water treatment system, the system comprising: (i) a chemical disinfectant and a flocculating agent, to treat water; and (ii) a deformable container comprising: an opening to receive water for treatment into the container; an internal storage region for holding an amount of water; a partitionable region fluidly partitionable from the internal storage region for separating the flocculating agent upon settling after exposure to water in the container; and an outlet in fluid connection with the internal storage region to remove water from the container.

The object of the invention is a personal and foldable device for the purification of water, which is used to filter water by means of the action of a removable filter whose function is to filter the water obtained in any medium, in order to improve the conditions of the same and make it suitable for human consumption.

This device is fundamentally conceived to facilitate its use in any place due to its particular compact and deployable configuration that makes it easily transportable, maintaining the water filtering and purifying performance for which it has been conceived.

The device comprises an upper body or deployable filter, which incorporates the filter and a lower body or carrier, deployable and removable with respect to the upper body, in which this lower body consists of a container itself that is designed to consume the purified water that passes through the filter of the upper body.
